About PHA Polyhydroxy Acids

PHAs are second-generation skincare acids that help to resurface and retexturize for a softer, plumper appearance and reduced fine lines. Locking in moisture, they build natural defenses and protect against external aggressors while their large molecular weight is slow-penetrating and gentler on sensitive skin.
